Cal Sweet Bush Watermelon
✓ In your garden
Cal Sweet Bush is an icebox watermelon, ready in about 85 days. It’s an icebox type — small, fridge-sized fruit that ripens faster. Watermelons need a long, hot summer, full sun, and room to run — plant well after frost. It’s ripe when the curly tendril nearest the fruit dries brown and the ground spot turns creamy yellow.
“A sweet summer watermelon for a long, hot season.”

Growing Cal Sweet Bush — the things that trip people up
- Melons are heat-lovers with big appetites — give them full sun, rich soil, room to sprawl, and a long warm season. In short-season areas, start them indoors and use black plastic or a cover to warm the soil.
- Ease off the water as the fruit ripens — too much late water dilutes the sugar. Judge ripeness by the dried tendril and the creamy-yellow ground spot, not by thumping.
